1. 18.03 Differential Equations

   • 1: Intro & first methods
     • A DIFFERENTIAL EQUATION is a relation between a function and its derivatives.
     • DE model a system to predict its long term behaviour
     • e.g. Newton's law F = ma
       • 2nd ODE because a=acceleration is derivative of x=positions
     • y' = F(x,y)
       • first derivative (first order)
       • ' means derivative in math
